CVE-2026-89617

A flaw was found in the Linux kernel's NTFS3 filesystem driver. An attacker with local access could craft a malicious NTFS log file. During log replay, insufficient validation of the lcnsfollow field in a DIRPAGEENTRY could lead to an out-of-bounds write. This memory corruption could result in a...

CVE-2026-89530

A flaw was found in the Linux kernel's svcrdma component, which handles network communication using Remote Direct Memory Access RDMA. A remote attacker can send a specially crafted network reply that is larger than expected. This can cause the system to write data beyond the intended memory area,...

CVE-2026-89509

A flaw was found in the Linux kernel's RDMA/ionic driver. This vulnerability arises from the driver's incorrect handling of rdmacounter allocations, specifically by not embedding counter driver data as required. This oversight can lead to a NULL pointer dereference when the allocandbind function ...

CVE-2026-31431 — Fallo de "copia" en algifaead del kernel Linux: Análisis Investigación de seguridad sobre CVE-2026-31431 CVSS 3.1 7.8 ALTO , AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H: tres fallos de diseño componibles en la cadena AFALG AEAD se combinan en una escritura determinista y sin condiciones ...

CVE-2026-89709

A flaw was found in the Linux kernel's lockd and nfsd components. An unguarded dereference of nlmsvcops after the nfsd module is removed can lead to a NULL pointer dereference or a use-after-free condition. This vulnerability could allow a local attacker to cause a denial of service...

CVE-2026-80977

A flaw was found in the Linux kernel's networking subsystem. The skbtxerror function improperly handles shared zerocopy state in socket buffers skbs. When a cloned skb is processed, it can prematurely signal that its pages are free and drop shared fragment flags while the original skb is still in...

CVE-2026-89723

A flaw was found in the nilfs2 file system component of the Linux kernel. When a file is truncated, an intermediate node block is not properly deleted and remains in the B-tree node cache. This can lead to the log writer incorrectly processing the block, resulting in a slab-out-of-bounds memory...

CVE-2026-89628

A flaw was found in the Human Interface Device HID picolcd driver in the Linux kernel. A local attacker with root privileges, by using a specially crafted or spoofed picoLCD device, could exploit an out-of-bounds read vulnerability in the picolcddebugeepromread function. This flaw occurs because...

CVE-2026-89609

A flaw was found in the eCryptfs component of the Linux kernel. A race condition occurs during the cleanup of the daemon message queue because a required lock is not held. This can lead to unpredictable system behavior or instability due to concurrent access to shared message context lists...

CVE-2026-89605

A flaw was found in the ecryptfs component of the Linux kernel. When the ecryptfssendmiscdev function fails to send a message to the userspace daemon, the associated message context is not properly released. This oversight leaves the context on an allocated list, preventing its reuse. Repeated...

CVE-2026-89581

A flaw was found in the Linux kernel's handling of Berkeley Packet Filter BPF programs on x86 architecture. An issue with how per-CPU addresses are resolved into extended registers can lead to incorrect memory access. A local attacker could exploit this by running a specially crafted BPF program...

CVE-2026-89565

A flaw was found in the Linux kernel's IP over IP ipip tunnel driver. When operating in collectmd mode, the ipiptunnelrcv function fails to free a network packet buffer skb if the metadatadst allocation fails. This oversight leads to a memory leak. A local attacker could potentially exploit this...

CVE-2026-89485

A flaw was found in the lockd component of the Linux kernel. This use-after-free vulnerability occurs in the nlmtraversefiles function when a file's memory is prematurely released while an iterator still holds a pointer to it. A remote attacker could potentially exploit this to cause system...

CVE-2026-89481

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express over TCP nvme-tcp component. A malicious NVMe controller can exploit this vulnerability by sending a Ready to Transfer R2T command for a read request. The host system, failing to properly validate the request direction, will...

CVE-2026-89461

A flaw was found in the Linux kernel's max17040 power supply driver. A timing issue, known as a race condition, can occur during system suspend. This allows a background process polling callback to continue accessing the fuel gauge and restart itself even after the system suspend has finished. Th...

CVE-2026-89447

A flaw was found in the Linux kernel's iommufd subsystem. A local attacker could exploit a vulnerability where an object reference is leaked during the unmapping of internal accesses. This occurs because the iommufdaccessnotifyunmap function incorrectly locks an object before checking if the acce...

CVE-2026-89436

A flaw was found in the Linux kernel's panasonic-laptop driver. This vulnerability involves an out-of-bounds write when processing ACPI SINF packages, where a small amount of data is written beyond the intended memory buffer. This can lead to a heap overflow, which might cause system instability ...

CVE-2026-89678

A flaw was found in the Linux kernel's Network File System NFS daemon nfsd component. The nfsddirectwrite function, responsible for handling direct writes, incorrectly detects partial writes. This issue occurs because the logic for detecting short writes compares the actual bytes written against ...

CVE-2026-89528

A flaw was found in the Linux kernel's svcrdma component. A remote attacker could send specially crafted Read lists that exceed the page budget. This can lead to a NULL pointer dereference during Direct Memory Access DMA mapping, potentially causing a system crash and a denial of service...

CVE-2026-89506

A flaw was found in the Linux kernel's RDMA/uverbs component. A missing update to the UVERBSMETHODREGMR ioctl allows a malicious userspace program to trigger a null pointer dereference in specific RDMA drivers mthca, irdma, siw. This can lead to a system crash, resulting in a Denial of Service Do...
